A three‑hour, family-focused rafting run on the Gallatin River that trades white‑knuckle drops for punchy, splashy rapids. Ideal for first‑timers, families, and anyone who wants scenic canyon paddling without long technical rapids.

The Gallatin River runs with a playful, restless energy here: clear, cold water that pushes and teases as it threads through narrow canyon walls and stands of lodgepole and Douglas-fir. On the Upper Half Day run you launch near Mile Marker 64 on Highway 191 and, within minutes, you’re paddling through a sequence of short, punchy rapids—Hilarity Hole, Screaming Left, and Killer Fang—that splash without requiring expert technique.

High visitation stresses riparian zones—practice Leave No Trace, pack out waste, and stick to established launch and pullout points to protect riverbanks.
